HOUSTON - (Dec. 15, 2020) - You have to look closely, but the hills are alive with the force of van der Walls.
Rice University scientists found that nature s ubiquitous weak force is sufficient to indent rigid nanosheets, extending their potential for use in nanoscale optics or catalytic systems.
Changing the shape of nanoscale particles changes their electromagnetic properties, said Matt Jones, the Norman and Gene Hackerman Assistant Professor of Chemistry and an assistant professor of materials science and nanoengineering. That makes the phenomenon worth further study.

A transmission electron microscope image by Rice University scientists shows a silver nanoplate deformed by a particle, forming flower-shaped stress contours in the material that indicate a bump. Changing the shape of the material changes its electromagnetic properties, making it suitable for catalysis or optical applications. (Credit: The Jones Lab/Rice University)
